VTo all whom t may concern:

Buttons, of which the' following is a specication.

The button of the present invention is intended for use with gloves,suspenderagarters, Uhand-bags, or similar articles'g-ofy-Wear--'ing-apparel in which a snap-buttonoff mall size is desirable; andtheobject of the `resent invention is to so construct :the .button l andsocket members ofthe device thtfwhen showing 'inafter described andclaimed.

one is inserted into the other an'd turned-it" Awill be impossible to?disengage the lparts from one another by mere`tension,' butwill benecessary to`l rst compressl the .buttonl member and then turn it apartial'revlolution in order to disengage the button frorirthc socket.This renders the device peculiarly suitable for securing hand-bags o rpurses-` 'against robbery and securing any articles which are ordinarilysubjected toa considerablestrain or tension, which often tends todisengage a snap-button of the ordinary type.

The invention consists in the features of construction and combinationof In the drawir.` gs, in which the members are shown greatly enlar ed,Figure 1 is a sectional view show-ing tglle button-shank inserted intothe socket; Fig. 2, a similar -view showing the `button compressedtoallow of disengagement; Fig. 3, a sectional view taken at right anglestothe section of Fig. 1, showing the shank in position to be removedfrom t e socket; Fig. 4, a sectional `'View the members disengaged onefrom the other; F igfl5, a face view of the socket; and Figs. 6, 7, and8, fragmentary details of the stud, showing the method of securing thepin therein.

In the drawings, 9`indicat'es-ithe button member, and 10 the socketmember, which members are secured to sections' of fabric or leather 11and12-,respectivel The button member comprises around liead 13, milled'around its edge 1.4, and a stud 15, which inwardly projects fromv thecenter of the head. The stud passes through and is embraced by abow-shaped flat spring .16, which bears against the inner face of thehead,and the stud has secured within its inner end a crossparts herevpin17. The cross-pin lies within a groove or recess 18 in the'elld ofthestud, and after the pin has been laidf-inplace the walls of the recessare upset, asi'shown in Fig. 7, to form in- .wardlyprojecting tonguesl19, which are embedded Jwithin a transversely-extending groove or cut 20in the .centerof the in 18. Thisarrangement holds the pin firm y andrigidly in place and prevents its displacement. The .stud Vpassesthrough inner and vouterwashers21 and '22, respectively, between whichthe fabric 11 is clamped, and

one of the Washers is preferably provided with a neck' 23, which passesthrough the fabric and the companionwasher and has its rim 2,5 upsetintoan annular groove or recess 26 inthe companion washer. This arrangementprovides a bearing for the stud and at the sametime serves.y to morefirmly hold together the two washers and clamp the fabric l betweenthem.

The socket comprises a' body portion 27, having on itslrinnerortengaging end an enlarged diskshaped head 28, provided in its ycenterwitha circular hole 29 of a suitable size to Ipermit easy insertionV ofthe stud, and the ho e Ion opposite sides merges into keyhole-slots 30,asbest shown in Fig. 5. Within the body of the socket is a circularchamber or recess 31, having a diameter substantiall equal to thedistance from end to end of the lkeyhole-slots, which arrangementprovides anv overhanging wall 32 around Ithe major portion of thecentral hole 29. At right angles to the slots 30 and on theinner face ofthe overhangingwalls 32 are formed a pair of recesses 33' for the recetion of thev ends of the cross-pin 18 after te ,stud has been insertedinto the socket. The body 27 is provided with a neck 34, which is passedthrough a washer 35 and'has its-edge or lip 36 u set into an annulargrogve or recess 37, Whic surrounds the opening in the washer.

In use when it is desirable to insert the shank of the button memberinto the socket the cross-pin on the shank is turned into a properposition to enter the keyhole-slots 30, permitting the stud to beentered into the central hole 29. (Best shown in Fig. 3.)- When in thisosition, the bow-spring will be uncompresseti but byl pressing thebuttonhead 14 against the tension of the spring the stud may be insertedto a sufficient degree t0- bring the cross-pin in line with the circularrecess or chamber 31 and in position to permit the button to be turnedat right angles to IOO ' ric.

disk-shaped head of the socket, which, in'

the initial position to the point indicated in Fig. 2. This turning willbring the pin in line with the undercut recesses 33 in the overhangingwalls 32, after which by relieving the pressure on the button-head thestud will be retracted by the tension ofthe spring, thereby holding theends of the pin within the recesses provided for their reception. Whenthe parts are thus engaged, it will be impossible to disengage themwithout performing the operations of initially compressing the button,then turning the button and afterward retracting the button over thesocket. At the same time the operation is one which can be very easilyperformed, in

view of the fact that the compressing and turning of the button willconstitute practically a continuous operation. No amount of tension,however, will serve' to disengage the arts, and .this fact renders thebutton high y `su erior to the snap-button ordinarly usedJ on gloves,lwhich can be disengaged by a pull or tension and which after continuoususage for -a short time becomes so loose and worn that the parts willbecome disengaged lon the slightest provocation. The buttonof thepresent invention, moreover, is one which presents avery neat andattractive ap earance, the only parts ordinarily exposed ,being themilled head and the face of the socket-disk.

The principal parts of the button can be made out of gold or silver, ifdesired, or can be decorated with pearl or gems, so that the button as awhole is one which will be found highly satisfactory for the pur osesintended. The inner and outer waslhers not only serve to provide arecess for the manipulation of the stud, but also serve to clamp thefabric tightly between the washers, which prevents tearing ordisplacement of the fab- The same is true with respect to thecombination with the washer 35, serves to clamp the companion section offabric and prevent tearing or displacement.

The mode of securing ap licants button and socket to the fabric ena lesthe parts to bination with two companion sections ofv material', a studadapted to outwardly project from one .of the sections, an enlarged flathead on thestud adapted to be manipulated by the thumb and finger, amounting for the stud comprising inner and outer washers on the oppositesides of the section through which the stud is passed, a spring betweenthe head of the stud and the outer washer for normally holding the headand stud retracted, a transverselyextending pin in the end of the stud7a socket secured to the companion section of material and comprising anenlargedvdisk-shaped head adapted to abut against one side ol' thematerial, a body of less diameter thanthe diskshaped head andpassingthrough the inaterial,a neck outwardly projecting beyond thebody, a washer surrounding the neck and secured thereto and adapted toabut against the material and clamp the material between said washer andthe diskshaped head, the socket being provided with a circular holeofsuitable diameter to permit' the rotation4 of the cross-pin, said holebeing provided with overhanging Walls having therein a keyhole-slot, andthe overhangin further provided lon their un er face with recesses intransverse relation with respect to walls being the keyhole-slot and:ofa size to receive the y cross-pin when` entered through vthe keyholeslotand turned into transverse relation thereto, substantially as described.
